Traevon Jackson followed with three free throws, but missed one with 21 seconds left to give the Ducks (24-10) one more chance to tie trailing by three.

Oregon gave it to Joseph Young, who had made big shots all night and scored 29 points. But he missed a rushed three-point attempt from the wing, and the Badgers sealed it at the foul line.

The red-clad fans erupted into a deafening roar. Their beloved Badgers are back in the regional semifinals for the first time since 2012.

Frank Kaminsky led the way with 19 points, Jackson finished with 16 and Brust had 12.

The Badgers trailed by 12 at the half, then rallied by getting the ball inside, where they had an advantage over the quick Ducks.

Young hit a three-pointer from the wing with 2:50 left to give Oregon a 75-74 lead.

The Badgers hustled for offensive rebounds on their next possession. Off a timeout, coach Bo Ryan re-inserted Brust, who was saddled with four fouls.

The senior delivered in a huge spot.

Jason Calliste had 20 points for Oregon, which set the tone early with in-your-face defense and an aggressive offense.

Wisconsin found its groove by attacking the basket with Kaminsky and its backcourt of Jackson, Brust and Josh Gasser. Sam Dekker added 12 points and eight rebounds in another typically balanced effort.

Left off-kilter by the Ducks transition game early, the Badgers hustled back in the second half to answer the Oregon charge and frustrate their foes in the half court
